The Limitations of Animal Testing
Animal research plays a critical role in scientific advancements, with approximately 100 million animals used annually for studies. Despite breakthroughs such as the COVID vaccine, about 90% of new drugs that show promise in animal models fail in human trials, highlighting significant limitations in extrapolating results from animals to humans. This discrepancy raises ethical concerns regarding the harm caused to animals in experiments that might not yield reliable outcomes for people. The push for alternatives to animal testing becomes urgent as scientists question whether current methods adequately represent human physiological responses.
